ROAD GRADER, SCRAPER, AND WEEDER.

SFECIFIGATION forming part of Letters Patent N 0. 700,923, dated May 27,1902.

Application filed November 18, 1901. Serial No. 82,699. (No model.)

To to whom it may concern.-

Be it known thatI, CHRISTOPHER HENDER- SON, a citizen of the UnitedStates, residing at Montrose, in the county of Montrose and State ofColorado, have invented a new and useful Road Grader, Scraper, and\Veeder, of which the following is a specification.

My invention is an improved road grader, scraper, and weeder; and itconsists in the peculiar construction and combination of deviceshereinafter fully set forth and claimed.

In the accompanying drawings, Figure 1 is a perspective view of myimproved machine, showing the same provided with the scraping andgrading blade. Fig. 2 is a detail sectional view of the same. Fig. 3 isatop plan View of my improved machine, showing the same provided with theweeding-blade. Fig. 4.- is a side elevation of the same with the nearwheel removed.

In the embodiment of my invention I employ an axle 1, on the spindles ofwhich are mounted a pair of supporting-wheels 2. A draft pole or tongue3 is here shown as attached at its rear end tothe center of the axle andalso connected thereto by brace-rods 4. A tool-box 5 may be carried onthe rear portion of the tongue. A pair of beams 6 have their front endsconnected to clips 7, the said clips being secured to and laterallyadjustable on the axle, whereby thefront ends of the said beams may bedisposed at any desired distance apart. Standards 8, which are curved,as shown, are formed integrally with the said beams 6 at the rear endsthereof, and the lower ends of the said standards are inclined, as at 9.

A frame 10 has its front end connected to the axle and its rearendsupported by a trailwheel 11, which is carried by a fork-frame 12,which has a vertical spindle 13, that turns in a bearing 14. at the rearend of the said frame. I will now describe the construction of the saidframe.

A pair of longitudinally-disposed bars 15, which are preferably made ofiron or steel and which constitute the sides of the frame 10, have theirfront portions diverged or forked, as at 16, and are arched, as at 17,to clear the beams 6. The front ends of the said bars are connected tothe axle 1, either as here shown or in any other suitable man ner. Across-bar 18, which is disposed at a suitable distance from the frontends of the bars 15, has its ends downturned, as at 19,the saiddownturned ends of said cross-bar 18 being bolted to the inner sides ofthe bars 15, as at 20. A centrally-disposed bar 21 has its rear portiondisposed between the rearwardlyextending portions of the bars 15, saidrearwardly-extended portions of said bars 15 21 being bolted together,as at 22. The bearing 14 for the spindle 13 of forkframe 12 has aforwardly-extending arm 23, which is disposed between therearwardly-extended portions of said side bars 15 and bolted in positionby bolts 24. The front portion of said bar 21 is arched and is bolted tothe center of the cross-bar 18, as at 25. A spring 26, which is boltedon the rearwardly-extending portions of the bars 15 21, carries a seat27 for the driver.

A rock-shaft 28, which is provided at its ends with cranks 29, isjournaled in bearings 30, which are bolted to the arched portions of theside bars 15. A segment-rack 31 is also bolted to one of said side bars,and to the said rock-shaft is attached a lever 32, which is providedwith a locking-dog 33 for engagement with said segment-rack, wherebysaid lever and the cranks of said rock-shaft may be disposed at anyadjustment.

A transversely-disposedbar 34 is disposed on and connects the rearportions of the beams 6. Said bar is provided with elongated slots 35,and the said beams are connected to the said bar by clips 36, whichoperate in said slots. Hence the beams may be adjusted toward or fromeach other, and by tightening the nuts 37, with which the said clips 36are provided, said beams may be secured at any desired lateraladjustment. Links 38 have their lower ends flexibly connected tothe bar34L by U-shaped bolts or other suitable devices 39. The said links areeach provided with a series of openings 40, and the wrists of the cranks29 of rock-shafts 28 may be engaged with any of the said openings of thesaid links. It will be understood that by means of the rock-shaft andthe connections hereinbefore described the rear ends of the beams may beraised or lowered to raise or lower the grading or weeding bladeconnected to the standards of said beams.

up in advance of the blade during the operation of the machine fromescaping therefrom at the ends thereof. The said sides 42 are angular incross-section and have the rear portions 43, which bear upon the frontsides of the blade 41 at the ends thereof and secured thereto by bolts44. At the lower edge of the said blade 41 and overlapping the same is ashare-blade 45, which is preferably made of steel and is secured on thelower portions of the standards 8 by bolts 46, the lower edge of theblade 41 being clamped between said share-blade and said standards 8 bythe said bolts 46.

In Figs. 3 and 4 of the drawings the Weederblade 47 is shown as securedon the inclined lower sides 9 of said standards 8 by the bolts 46, theblades 41 and 45 having been removed. The said weeder-blade has itsoppositelydisposed edges beveled and sharpened, as at 48, so that saidblade is adapted to be reversed when one of the edges thereof becomesdull. It will be understood from an inspection 'of Figs. 3 and 4 of thedrawings that when the machine is equipped with the said blade 47 thesame is adapted for use in destroying weeds, the front edge of the saidblade running under the surface of the soil at a slight depth andcutting through the roots and stems of the weeds and efiectuallydestroying them.

My improved machine may be also used for ditching and other analogouspurposes, is exceedingly cheap and simple, is very strong and durable,and is entirely eflicient when in operation.

Having thus described my invention, I claim- 1. A machine of the classdescribed, comprising a front axle and supporting wheels thereon,bea-m's having standards adapted for the attachment of an earthoperating blade thereto, said beams having their front ends slidably andpivotally connected to said axle, a cross-bar to which said beams areslidably connected, a frame attached to said front axle, a supportingelement for the rear end of said frame, a crank-shaft having itsbearings on said frame, a lever to turn said crankshaft, and a linkconnecting a crank of said shaft to said cross bar, substantially asdescribed.

2. In a machine of the class described, a frame comprising a pair ofside bars having their front portions diverged forwardly and arched, across -bar connecting said arched front portions of said side bars, anda centrally-disposed longitudinal bar, having its front portion archedand secured to said crossbar, the rear portion of said last-mentionedbar being disposed and secured between the rearwardlyextending portionsof said side bars, substantially as described.

3. In a machine of the class described, a frame havingforwardly-diverging side bars with arched front portions, a bearingsecured between the rear ends of said side bars, a forkframe, having avertical spindle journaled in said bearing, a trail-wheel carried bysaid fork-frame, an axle to which the front ends of said side bars areconnected, supportingwheels on said axle, beams having standards adaptedfor the attachment of an earth-operating blade thereto, said beams beingpivotally connected at their front ends to said axle, a bar connectingsaid beams together, a rockshaft journaled in bearings on said sidebars, said rock-shaft having an operating-lever and cranks, and links,connected to said bar and adj ustably connected to said cranks,substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

CHRISTOPHER HENDERSON.
